i had no idea this was a real version of the classic game
i looked it up

I sure hope this is a logically solvable puzzle. So here goes...scissors cut paper, paper covers rock, rock kills lizzard, lizzard poisons Spock, Spock destroys scissors, scissors decapitates lizzard, lizzard eats paper, paper disproves Spock, Spock vaporizes rock, & rock crushes scissors.

Most of this puzzle solves with color logic. Only the last bit of blue is left at the end. Some people would apply "diagonal logic", but that is not considered logically solvable.

However, we can apply summing logic to figure this one out. We are left with parts of rows 19-28 and columns 14-23 to complete. Looking at columns 14-17 we need a total of 8 blue cells filled in. Looking at rows 19-23, we need 9 blue cells filled in. This means we need exactly 1 blue cell in column 18 that is also in rows 19-23. The only way this is possible is if the 2 clue in column 18 is at R23C18-R24C18. The rest solves with line logic.

Very good example of the summing technique. Thanks for the puzzle Brian.

Found to be logically solvable by Gator.

Is "diagonal logic" not considered logically solvable because it requires too many steps ahead, Gator?

I managed to eliminate all but one possibility for where the NW pointing blue arrow should go, based on the position of the 1 blue pixel between the green and the blue in R19--the only place it made sense was C14. That was indeed a look-ahead (not terribly far, however). I didn't see the summing logic, though.

I really did enjoy solving this one in spite of that last tricky bit. And I think I first read about this version of the game as a t-shirt somewhere (maybe thinkgeek?)

I have that T-shirt. My lovely wife gave it to me as a solstice gift.

In this case the "diagonal logic" required looking more than two steps ahead.

I think I could more easily show the summing logic in this case with pictures. (Not sure if I'm going to go through that effort though.)

Logically solved, it needs more than two steps ahead. Nice puzzle, fun to solve.
thanks

I seemed to have solved it logically, that or just got lucky seeing the arrows. Nice Big Bang Theory reference.

Thanks Bengt. My favorite show.

where did all these native american indian arrows come from?
#12: Diana W (aeris) on Feb 20, 2011 [HINT] [SPOILER]
With the last red and blue arrow, I eliminated all but one option of where the start of the arrow could go, and then solved from there. I'm not 100% sure that my logic was okay, but it was an interesting challenge.

Very colorful but made no sense. Did a fair amount of guessing to solve this.

Likewise, I got to the end and employed what may be called "diagonal logic" for the last blue arrow, but I was considering it a flavor of smile logic. Maybe smile logic is actually a flavor of diagonal logic. Anyway, I was considering it logical because I imagined a blue diagonal line there, and saw that it would work, and therefore placed the blue squares accordingly.
